ErklärungThe light reactions split water to release oxygen and store energy in the form of ATP and NADPH for use in the Calvin cycle.
Phloem
Xylem
Cortex
Epidermis
ErklärungXylem is the specialized tissue responsible for the upward conduction of water and dissolved minerals from the roots.
Glucose production
ATP and NADPH
Carbon dioxide fixation
Starch accumulation
ErklärungLight-dependent reactions convert solar energy into chemical energy in the form of ATP and NADPH.
Mitochondria
Nucleus
Chloroplast
Ribosome
ErklärungChloroplasts contain chlorophyll, the pigment that captures light energy for photosynthesis.
Oxygen
Nitrogen
Carbon dioxide
Hydrogen
ErklärungPlants take in CO2 from the atmosphere to synthesize glucose through the Calvin cycle.
Auxin
Gibberellin
Ethylene
Cytokinin
ErklärungEthylene is a gaseous plant hormone that promotes fruit maturation and ripening.
Chloroplast
Mitochondria
Ribosome
Golgi apparatus
ErklärungMitochondria are known as the powerhouse of the cell because they perform aerobic respiration to produce ATP.
Xylem
Phloem
Epidermis
Cortex
ErklärungPhloem is the vascular tissue responsible for translocation of organic nutrients like sucrose.
G1 phase
S phase
G2 phase
M phase
ErklärungDNA synthesis or replication occurs during the 'S' (Synthesis) phase of interphase.
Respiration
Photosynthesis
Transpiration
Absorption
ErklärungTranspiration is the evaporative loss of water from the aerial parts of a plant, primarily through stomata.
Carotene
Chlorophyll
Xanthophyll
Anthocyanin
ErklärungChlorophyll is the primary pigment that absorbs light energy, primarily in the blue and red regions of the spectrum.
Stamen
Anther
Ovary
Petal
ErklärungThe male gametes travel to the ovary where they fertilize the ovule, which then develops into a seed.
